I ran the Miele last night after dinner. This morning when I opened it up to retrieve the coffeemaker carafe, I found the upper rack (second tier for glassware, etc.) wash arm sitting on top of the items in the lower rack. It was easy to figure out how to re-attach it, but I'm wondering what caused this.
If there's anything in the lower rack that might create an obstruction, I always give the upper arm a spin to make sure it clears. The only thing I can think of is that maybe something shifted and blocked the arm, and somehow the connection point remained spinning while the arm wasn't, and the arm detached. Or maybe it just worked itself loose over the 4+ years I've had this machine. There's no good way to grip the hub where the arm attaches when tightening it, and I suspect it's a hand-tighten design.
This must have happened late in the game because there was a plastic cooking spoon with hardened cheese and other stuff stuck to it in this rack, and it came out clean. Any other theories on why this happened?
